These options were granted pursuant to the Issuer's 2019 Equity Incentive Plan (the "Plan"). 25% of the shares underlying the option shall vest on April 21, 2026, and the remaining shares subject to the option shall vest in twelve (12) equal quarterly installments thereafter, subject to the Reporting Person's continuous service to the Issuer or an affiliate on each such date. | These capped value appreciation rights ("CVARs") will vest on the first date that each of (i) the Service Requirement, (ii) the Performance Requirement, and (iii) the Knock-in Requirement have been satisfied. The "Service Requirement" is satisfied as follows: (i) 25% of the CVARs vest on April 1, 2026; and (ii) the remaining 75% vests in twelve (12) equal quarterly installments thereafter, subject to the Reporting Person's continuous service to the Issuer or an affiliate on each such vesting date. The "Performance Requirement" is tied to the achievement of a specified clinical development activity at the Issuer. The "Knock-in Requirement" requires that the price of the Issuer's common stock at each applicable vesting date must be equal to or greater than $16.76 per share. | Upon satisfaction of the vesting conditions (such portion of the CVARs, the "Vested CVARs"), the Reporting Person will be entitled to receive a payment equal to the product of (i) the number of Vested CVARs multiplied by (ii) the excess (if any) of (A) the fair market value of the Issuer's common stock (capped at $16.76 per share) as of the relevant date of determination over (B) the applicable hurdle price of $14.46 (the "CVAR Amount"). The CVARs will then settle into a number of shares of common stock of the Issuer determined by dividing (i) the CVAR Amount by (ii) the fair market value of the Issuer's common stock as of such date.
